No. I.] ACTINIARIA OF THE BAHAMAS. 27 
The form described by Lesueur (17) from St. Vincent as 
Actinia bicolor has been assigned by Gosse (’60) to the genus 
Bunodes. In coloration it resembles 2B. teniatus, the column 
being “divided longitudinally with brown and white bands,” 
and the tentacles having “a row of white spots on the superior 
part.” In other respects, however, there appear to be decided 
differences, and, judging from Lesueur’s description, his A. dzco- 
Jor should be assigned to the genus Adamsza, as has been done 
by Andres (83). The limbus only is furnished with tubercles, 
of which, however, there are several rows; and in habit also it 
resembles the members of the genus Adamsza, being found 
adhering to shells. 
There seems to be a good deal of probability that B. tenzatus 
is simply a color variety of Lesueur’s Actinza granulifera (17), 
which has been variously referred to the genera Az/actinta, 
Oulactis, and Anthopleura. Among the forms figured by Uht- 
hoff, from Green Turtle Cay, is one evidently identical with 
Lesueur’s species. I did not find any specimens similar to that 
from Green Turtle Cay with which to compare my ZB. senzatus, 
and accordingly prefer to consider it distinct for the present. 
I have no doubt but that Lesueur’s A. granulifera is a Bunodes. 
Genus AULACTINIA, Verr. 
Synon. — Actinia (pars) —L. Agassiz, Ms., 1849. 
Aulactinia — Verrill, 1864. 
Bunodide, with the upper portion of the column provided 
with longitudinal rows of verrucz, the lower portion being 
smooth. The margin forms a more or less distinct collar, and 
the tentacles are polycyclic and entacmzous. The six pairs of 
mesenteries of the first cycle are alone perfect. 
Verrill, who first defined this genus, seems to have placed too 
much importance upon the lobation of the upper verrucze, which 
were considered acrorhagi, and in this Andres has followed 
him. The essential peculiarities of the genus, as it is under- 
stood here, are the limitation of the verrucz to the upper part 
of the column, and the small number of perfect mesenteries. 
This latter characteristic I have found to hold in A. cafitata, 
the type species of the genus.
